Coloradans are split on statewide ballot initiatives but support the impeachment of President Donald Trump, according to a new survey from the University of Colorado-Boulder.

The fourth annual Colorado Political Climate Survey involved 800 registered voters in the week prior to election day.

Half of respondents said they would not vote for Proposition CC, the measure to eliminate refunds under the Taxpayer Bill of Rights (TABOR) and invest the money in education and transportation. Forty-three percent said they would vote yes, and 7% were undecided.

The result in the online poll was within the 3.5% margin of error, but the survey’s authors caution that CC “does appear headed to defeat.”

The survey also has asked about support for TABOR itself every year. Roughly half of respondents are in favor of the 1992 constitutional amendment to limit tax revenue, while between 20% and 30% oppose it.

While the percentage of people who “favor” TABOR has halved in the past four years, the percentage that “strongly favors” it has increased by 12 points.

By comparison, strong opposition has only increased by four percentage points.

Predictions for the fate of Proposition DD are clearer, with 62% of respondents planning to vote yes on the measure to legalize sports betting. Democratic, Republican and unaffiliated voters all gave the proposal majority support, although there was only a four point difference for Republicans between support and opposition.

Finally, the survey asked a sample of all Coloradans, not just registered voters, about the feelings on the U.S. House of Representatives’ impeachment inquiry into Trump.

Forty-seven percent strongly favor impeachment, with an additional 9% who favor it. Thirty-one percent strongly oppose, and 6% just oppose.

Unsurprisingly, support is highest among Democrats, nearly 90% of whom support impeachment. A slim majority of unaffiliateds are in favor, while 78% of Republicans oppose it.

The survey ended on Nov. 1, one day after the House voted on the rules of its impeachment inquiry.
